No it's not.
People need to get realistic here.
Yes, Ty did well in the short time he was on but we need to see a lot more of him before we can say he is Seamus's understudy.
If Seamus is still not fit you can bet Bobby will start Tony at OT.
The thing for me is that you would like to think that Browning has a lot more to come in his game. It seems unlikely that Hibbert has a lot more improvement left in him. As both are at similar levels now, it makes sense therefore to play Ty rather than Tony, doesn't it?
